RAKE-STRAlGl-ITENING DEVICE.

SPECIFICATION forming part f Letters Patent No. 277,077, dated May 8,1883.

Application filed July 10, 1882. (No model.)

To all whom it may concern: Be it known that I, GEORGE N. SWEET, oAshtabnla, in the county of Ashtabula and State of Ohio, have inventedcertain new and useful Improvements in Devices for Straightening Rakes;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it pertains to make to and use the same.

- 7 My invention relates to a device for straightening rakes; and itconsists in the peculiar construction of the same, as will be hereinafter fully set forth and claimed.

In the drawings, Figure 1 is an isometric view of a rake-straighteningdevice embodying my invention, showing the sliding die of the same drawnback. Fig. 2 is an isometric view of my device, showing the sliding diein position while the rake is being operated upon by a press or hammer.Fig. 3 is a vertical cross-section taken through my device, showing theposition of the parts before the teeth of the sliding die have beeninserted between 2 the rake-teeth. Fig. 4 is a vertical cross-sec- 7tion takcn through my device, showing the position of the parts afterthe teeth of the sliding die have been inserted between the teeth of therake, also showing in section a 0 hammer and its position whileoperating on the rake.

A is the bed of my device, which maybe formed either of one or twopieces. I prefer to make it of two pieces, as shown, as a matter ofconvenience in forming the central groove.

B B represent the two sides or uprights of a press or steam-hammer,between which the bed A is secured, if desired or it may be secured tothe bed-plate ot' the press or steamhammer, the manner of securing itforming no part of my invention.

(t is a recess formed in the bed A, into which lit the teeth of therake.

5 O is a sliding die, which is provided with teeth I) b. These teeth I)b are formed tapering or wedge-shaped, and at such distance apart as toadapt them to enter between the teeth of a rake, as shown in Fig. 2, andsup- 50 port the back from below. The points of the teeth I) b of thesliding die are supported in 7 turn by resting on a ledge, d.

D is a guide-rod, of which there are two,

one on each side of the bed A; but any means for guiding the sliding diemay be used.

One means for operating the sliding die O is shown in the drawings,which consists of the pivoted lever E, one end of which is attached tothe rod or bar F, which in turn is secured to the sliding die, (seeFigs. 3 and 4;) but it is obvious that any suitable device may be usedthat will operate to slide the die 0 back and forth.

G is meant to represent a hammer, which is designed to be of at leastthe same length as the rake, or that part of it which is to be operatedupon.

H is a rake.

The operation of my device is as follows: The rake, or that part of itto be operated upon, being heated, is first so straightened as to bringall the teeth in the same horizontal plane. The rake is now inserted inthe recess a, teeth downward, as shown in Fig. 3, it being supported atthe sides by the plates cf, which are secured to the bedA in such amanner as to allow the teeth of the sliding die 0 to pass under them.(See Fig. 4.) After the rake is inserted, as above described, thesliding die 0 is brought to the position shown in Figs. 2 and 4. Thepress or hammer G is then brought down and the edge of the back of therake is straightened.

What I claim is 1. In a device for straightening rakes, the combination,with a bed-piece, of a sliding die, said die being provided with teethadapted to enter between the teeth of a rake, substantially as and forthe purpose shown and described.

2. In a device for straightening rakes, the combination, with the bed A,provided with a recess for the admission of the teeth of a rake, ot' asliding die provided with teeth adapted to enter between the teeth of arake 5 and support the back from below, substantiallv as and for thepurpose shown and described.

In testimony whereofl have signed my name to this specification in thepresence of two sub- 10o scribing witnesses.

GEORGE N. SWEET.
